T 0 all whom it may concern.

Be it-known that I, HUGH SNOWIE Homes, of Carlton, Arkwright Road, Hampstead, in the county of London, England, have invented certain new and useful Improvements in or Relating to Treeing Devices for Boots and Shoes, for which I have filed an application in Great Britain, May 16, 1917, Patent No. 112,231, of which the following is a specification v This invention has reference to treeing devices of the kind comprising a front or foot portion and a rear or heel portion jointed togetherlby an adjustable intermediate link device embodying aspring, the front or foot portion being designed. to fit the forward portion of a boot or shoe, including the instep and toe portions thereof, and the rear or heel portion to fit against the heel of the boot or shoe, the intermediate link device serving to admit. of the treeing device being inserted in the boot or shoe (hereinafter referred to as a boot) and the spring serving tok eep the parts of the device and the boot in which they are inserted, in the desired expanded or stressed condition.

Now the present invention has reference, in treeing devices of the kind referred to, to a simple and efi'ective construction and arrangement of the intermediate link device and of the arrangement and actuation of the spring.

For this purpose in aatreeing device according to the invention, the foot and heel portions of the device are connected together by an intermediate multiple link arrangement, such that upon the device being moved into its operative position the front member of the multiple link arrangement will be caused to assume a more or less horizontal position and the rear link to assume a more or less vertical position thereby compressing the spring which acts to force the foot and heel portions of the device apart and subject the boot to the desired treeing action. According to one example, the intermediate multiple link arrangement may comprise two links, namely a front one and a rear one, the latter being preferably in the form of a plate. The spring inclosed in the heel portion of the device is arranged to be compressed by the rear link when the device is placed in a boot and the front heel portions forced apart. The plate-like link may conveniently be'connected to the heel portion of the device by jointing it at its upperend to a second plate fixed to, the front side of the said heel portion and formed with a hole through which extends a flanged-plunger. for compressing the spring when the movable hinged plate is pressed toward the fixed plate. The two plates in this case form an ordinary butt hinge. I

;To render a treeing device according to the invention adjustable for bootsof dilferent lengths, the link can be made in two parts capable of sliding endwise relatively to one another and of being readily fixed in their adjusted position, by a'spring actuated pin. The two "parts of the link may bearranged to slide one within the other, telescopically, or one against the other, sidewise.

To admit of the foot andheel portion "of the treeing device with intermediate. link arrangement being folded up one 'against the other to facilitate packing, the foot portion of the device may be made more or less concave on and along its underside to accommodate the heel portion and link arrangement.

As will be obvious, a treeing device according to the invention can be constructed in various forms.

In the accompanying illustrative drawings, Figures 1 and 2 show respectively in side elevation and'central longitudinal section, one construction of treeing device according to the invention.

Fig. 3 is a cross sectional elevation on the line A, A, of Fig. 1. Fig. 4 shows the position of the parts of the device folded up for packing.

Referring to Figs. 1 to 4, a is the foot portion, 6 the heel portion and 0 and (Z the front and rear links of an intermediate double link arrangement. The front link 0 is jointed by a pin 6 to the foot portion a and the rear link d is jointed by a pin 7 to the upper part of a plate 9 fixed to the front side of the heel portions 6, the two links being jointed together by a pin it, the arrangement being such that the rear link d can assume a more or less vertical position as form of a plate jointed to the plate 9 by the pin 7 the two plates and pin resembling an ordinary butt hinge. 2' is a coiled spring housed in a recess j in the heel portion band k is a push device the inner end of which is flanged and bears against the spring and the outer end of which extends through a hole on in the plate g so that it can be pressed inward, to compress the spring '5, when the plate link cl is moved down against it, The push device 70 may be recessed at its inner side and the forward end of the spring 2' be arranged to extend into it.

The front link 0 comprises two tubes arranged to slide telescopically one within the other, the inner tube carrying a spring pressed pin a adapted to enter any one of a series of holes 0 in the outer tube. The arrangement is such that by pressing in the pin it by a finger against the action of its spring 71 the two parts of the link can be moved endwise relatively to one another and the pin allowed to reenter another hole 0 and firmly hold the said parts in their adjusted position. The front end of the inner tube and the rear end of the outer tube are adapted to be j ointed'by the pins 0 and h to fixed lugs 12 and 1 on the foot portion a and link d respectively. 8 is the ordinary finger piece fixed on the foot portion a to facilitate removal of such portion from a boot.

The foot portion a is hollowed out on its underside to form a cavity 6 for the reception of the multiple link arrangement 0, and heel portion 6.

The foot and heel portions 04 and Z) may be of wood and the remaining portions of the device he of metal.

I claim.

' 1. In combination with the front and heel members of a boot tree, a link pivotally connected to the front member, a plate hingedly connected at its upper end to the rear member and also pivotally connected to said link, and a spring arranged in a recess in said heel member and exerting tension against said plate to normally hold said plate at an angle with respect to said heel member.

2. In combination with the front and heel members of a boot tree, a link pivot-ally connected at its front end to thefront member, a plate hingedly connected at its upper end to the front side of said heel member, and also pivotally connected to the rear end of said link, a spring arranged in a recess in said heel member, and a push device guided by said heel member and arranged to bear against said plate and also against said spring, so that said spring exerts its tension to normally hold the plate at an angle with respect to said heel member.

In witness whereof I afiix my signature in presence of two witnesses.

HUGH sNowrn JONES.
